3 Stress Type: Use Type: Recreation, Recreational Fishing, Tourism Based Industry Summary of Fisheries Studies / Reports: McIntyre, E Lake Trout Egg Collection Project Fall, 2001 The single lake trout captured had a total length of 59 cm. The single walleye also reported captured had a total length of 59 cm. Netting results were poor in 2001 and 2000, relative to the inaugural year of the project. In 1999, 21 lake trout were captured but only two in 2000 and one in 2001 McIntyre, E Lake Trout Egg Collection Report, Fall 2000 Only 2 lake trout were captured at the Birch Crest site and no lake trout were captured at the Twin Island site. Both fish were males and were released. No lake trout eggs were collected. The catch of lake trout at the Birch Crest site was much reduced from the previous year when 21 lake trout were captured. Likewise, 155 lake whitefish and 61 common white suckers were captured in 1999, but only 11 and 71 respectively in Fishing effort was slightly greater in 1999 with a total of 8 nights of netting effort versus 6 netting nights in We are unable to speculate on the cause of the poor catch results in 2000 especially lake trout. However, these results do lend additional credibility to speculation expressed in the previous year s report that lake trout are not spawning at the Birch Crest site. The catch of brown bullhead was up considerably: 23 in 2000 versus only 1 in Seven walleye were caught in 99, none in Concurrent with the netting project being conducted by Mr. Stewart, Ministry of Natural Resources staff conducted spawning site evaluation at all locations reported lake trout spawning sites (Blythe, 1989). Sites were visually inspected for lake trout eggs deposited on these sites using a remote viewing underwater camera. Not a single lake trout egg was observed at any of the sites. Spawning locations for lake trout in Sollman Lake remains unknown at this time. McIntyre, E Lake Trout Egg Incubation Study, Fall 1999 to Spring 2000 The lake trout catch from a total of nine net nights of fishing effort was a meager 21 fish or 2.3 lake trout per net night. Other species caught included: 155 common white suckers, 61 lake whitefish, 7 walleye, 2 rock bass and 1 brown bullhead. The low catch rate of lake trout (2.3 per net night) suggests either a very small spawning population or that our trapnet was not in the vicinity of where lake trout actually spawn. Thirteen (13) male lake trout were biosampled having a mean total length of 65.3 cm and mean weight of 2815 grams. Only two (2) female lake trout were sampled both of very similar size with mean total length of 66.9 cm and each weighing 2600 grams. The capture of 7 walleye is the first evidence that walleye are present in this lake. It is unknown if these are native fish from a natural range expansion (possibly via Sterling and Sollman Creek), or are these remnants of an unauthorized introduction by a member of

4 the public within the past decade or so. Despite a fair number of lake whitefish captured (6.8 per net night), as of October 29 th we saw no evidence in the form of egg deposition, that lake whitefish were using this area for spawning. From 38 lake whitefish sampled, mean size was 45.2 cm. total length. Approximately 2600 artificially fertilized lake trout eggs were loaded into three separate Scotty-Jordan incubators on October 24, All eggs were obtained from a single gravid female and fertilized with milt from several males. Dave Stewart reports hatching success rates of 79%, 69% and 64% for each of the incubators. We conclude that water quality conditions on Sollman Lake are satisfactory for successful lake trout egg incubation and that Scotty-Jordan egg incubators can effectively be used to incubate lake trout eggs and enhance hatching rates by eliminating mortality associated with egg predators. Intensive underwater (SCUBA) observation of lake trout spawning shoals was conducted along the shoreline of Birch Crest Resort on October 29, 1999.Spawning shoals that had been enhanced with rock deposition in 1998 were found to be heavily silted with absolutely no indication of any cleaning related to lake trout pre-spawning, milling-about activities We conclude that lake trout did not spawn in any of the area searched. McIntyre, E Spring littoral index netting report for Sollman (Horn) Lake, 1998 Chapman Twp. 9 lake trout caught for a CUE of 0.3 (very poor; low lake trout abundance) large bodied lake trout - mean total length 55.4 cm. mean wt. 1.8 kg. (N = 9) poor levels of recruitment and reproduction - but all lake trout sampled were naturals harvest controls are needed to allow the spawning population to rebuild and establish the Lake Trout as the dominant predator McIntyre, E Results of a non-intensive roving creel survey conducted on Sollman Lake during the summer of Nine sample days only; only angler hours sampled. Low fishing pressure: 1.7 boats per mid-day activity count. Smallmouth bass E.U.C. and E.U.H. were 4.9 and 5.7 hours respectively No lake trout were caught. Janoki, K Sollman Lake creel census, winter Volunteer Creel format reported fishing effort: 1,111 angler hours. 49% of effort targeted lake trout; 35% whitefish and 16% ling. 22 lake trout and 37 whitefish observed Lake trout mean total length: 46.7 cm. Observed lake trout catch & harvest: 82 and 48 respectively Observed whitefish catch & harvest: 49 and 46 respectively Observed ling catch & harvest: 91 and 89 respectively Lake trout EUC and EUH: 12.0 and 20.5 hours respectively Whitefish EUC and EUH: 13.5 and 14.4 hours respectively
